How to Insulate Your Garage Door

Insulating a home garage door will effectively aid in keeping the out heat during the summer months while doing the same for cold air during the winter. While the application won’t turn your area into a cool summer getaway all on it's own, it will help to make the environment much more enjoyable. The real benefit that comes from an insulation application is the ability to cool storage areas in hot regions where the sun beats directly onto the door. These conditions can effectively raise the temperature inside the garage 25 to 30 degrees, thus adding costs and discomfort to your summer and winter months. In this article, we will outline an inexpensive method which you can use to insulate your door.

Materials / Tools:

• Utility Knife or fine-toothed saw
• Industrial Adhesive
• ½" thick, foil-backed, poly insulation
• 1" thick poly insulation

Step 1 – Measure the height of each door panel. Cut the 1" poly insulation into strips that run 2" wide, and roughly 1" shorter than the individual door panel height.

Step 2 – With your industrial adhesive, glue each strip onto the individual panels of the door. Add two strips to the middle with one at each end. These will work as blocks to keep the next layer from coming in contact with the surface of the door.

Step 3 – Measure and cut the ½" reflective insulation into strips that correspond with each door panel. Be sure to cut them so that they are able to fit appropriately.

Step 4 – Position the insulation panels onto the back of the door. It may be possible to simply fit them into the doorframe sides depending on the design you're dealing with. Alternatively, you may even be able to glue them directly onto the poly strips that have already been placed. Evaluate your situation and move ahead accordingly.

Step 5 – You'll want to be sure that you are installing the insulation with the reflective side facing inward and not into the garage. The surface of the reflective material combined with the air space created will step the transfer from the surface into the garage.

If you’re having any doubts, or find yourself in a sticky situation, it’s always good to know you have the ability to call in a professional. Consulting a trained technician is always a good decision when you’ve met a cross roads in your work, if even for a different perspective on the situation.
